Excerpt from Practice and Theory of the Injector
TO henri jacques giffard, an eminent French mathe matician and engineer, belongs the honor of having invented the simplest apparatus for feeding boilers that has ever been devised, utilizing in a novel and ingenious way the latent power of a discharging jet of steam. From the time of his graduation from L' Ecole Centrale in 1849, Gifi'ard had directed his energies to the study of aeronautics and had spent much time in developing a light steam motor for propelling balloons; it is, therefore, not strange that he should also have attempted to devise a com pact and convenient substitute for the steam pumps then in use. Already a number of patents had been granted him for the application of the steam engine to aerial navigation and for other correlated inventions When, on May 8, 1858, letters patent Were issued for L' [njedeur Automoteur. His early technical education and wonderful ingenuity well fitted him for breaking away from the old beaten paths and start ing out on a new line of discovery; and in view of the originality of his work he fully deserved the unqualified praise accorded him by his contemporaries.

Paperback. Condizione: New. Print on Demand. This book explores the Giffard injector, an apparatus that uses the power of a discharging steam jet to force water continuously into a boiler. The injector, invented by Henri Giffard in 1858, was a significant advancement in boiler feeding methods, offering advantages over the unreliable and inefficient pumps of the time. The author thoroughly examines the theory and mechanics of the injector, providing practical insights into its design and operation. The book traces the development of the injector from its inception to its widespread adoption in locomotives and other applications. It highlights the contributions of various inventors and engineers who refined and improved upon Giffard's original concept, leading to the self-adjusting and re-starting capabilities of modern injectors. Delving into the injector's performance, the author quantifies its efficiency and analyzes the factors influencing its capacity and range. Different types of injectors, such as single-jet and double-jet, are compared, and their respective advantages and limitations are discussed. The book concludes by emphasizing the enduring significance of the Giffard injector, which revolutionized boiler feeding and remains a vital component in various industries today. Its principles have influenced the development of other jet-based devices, showcasing the injector's lasting impact on the field of fluid dynamics and engineering.
